UNITED STATES PATENT OFFICE.

JNO. GOULDING, OF WORCESTER, MASSACHUSETTS.

MANUFACTURE OF DOUBLE-PILE CARPETS A ND BUGS.

Specification of Letters Patent No. 16,437, dated January 20, 1857.

To all whom 'if may concern:

Be it known that I, JOHN GOULDING, of the city and county of l/Vorcesterand State of Massachusetts, have invented a new and useful Improvementin the Fabrication of Piled Goods.

It consists in a peculiar fabrication of piled goods woven double faceto face. In producing this kind of goods I use thirteen hundred threadsof worsted for a five frame figure, carpet three fourths of a yard wide,to produce a carpet of something like appearance of the above by the oldmethod of weaving there would be twenty siX hundred threads of the sameNo. of worsted yarn used, say No. 1Q. or 14, I get the same quantity onthe face by bringing up each draft of ligure warp twice, in the samespace the old method would make one.

I am not aware that there was ever a piece of carpet or even a sample ofcarpet woven in this way, or similar with jacquard, although there hasbeen a patent purporting to do something` in weaving double carpets, butnot like the above.

Sheet l Figure l, represents the edge of the carpet, as woven before itis cut apart, it is elongated and enlarged, so as to show thefabrication more clearly. This drawing shows the figure warp raised tentimes, which when closed up as it is woven will produce one half inch ofgoods in length.

A, is the lower fabric as it is woven B the upper fabric.

l and 2 is the lower ground or binding warps, 3 and 4 the upper groundor binding warp.

5 is a straight warp in the lower fabric.

6 is straight or stuliing warp in upper fabric.

7-7-7 is weft or filling in upper fabric.

8-8-8 is weft or filling in lower fabric.

9-10-11-12 and 13 represent a five frame so called or five colors,represents the figure warp usually worsted, not confined to any numberof frames. The length of pile depends on the distance they are keptapart when woven.

Sheet 1, Fig. l, l is the shoot of filling thrown in the lower web, theweb being sprung to receive the weft, in between the yarn. 2 is theshoot in top fabric, these two shoots are thrown one at the bottom, andone at the top. The next 3 3 is top and bottom both at once. 4-4 are twomore shoots top and bottom both at once. 5-5 are two more shoots top andbottom both at once. The top binds one loop of Worsted with two shootsof filling in one stitch. The bottom two successive loops of worsted,and four shoots of filling in one stitch. In the upper fabric thefilling is thrown alternately above and below the stuffing warp G. Thebottom fabric the straight warp 5 runs with worsted, three shoots aboveand one below. In throwing eight shoots of weft bring the lower groundwarp in the spring of shed, as when commenced as above, and so onweaving.

Having now described and particularly ascertained the nature of my saidinvention and the manner in'which the same is or may be combined orcarried into effect, what I claim and desire to secure by Letters Patentis`a The fabric made or woven in the manner described, that is to say,crossing the top ground warp once only for two shoots of binding fillingone of which passes through and binds the pile warps; and crossing theground warp of the bottom fabric once only for four shoots of thebinding filling, three of which pass through and bind the pile warps.

In testimony whereof I have herein signed my name.

JOHN GOULDING. Witnesses:
